Method for generating a rights object, method and system for limiting a rights object
摘要:
Discloses are a method for generating a rights object, and a method and apparatus for limiting a rights object. The method for generating a rights object includes: after the rights issuance system receives the rights information relative to the content object, the rights issuance system determines whether the rights object to be generated is a stateful rights object and has copy export permission according to the rights information, and performs subsequent processes for generating the rights object if it is not a stateful rights object or does not have the copy export permission. The rights issuance system further determines whether the rights information includes state limitation information for the copy export permission when the rights object to be generated is a stateful rights object and has the copy export permission. If it does, perform subsequent processes for generating the rights object. Otherwise, abandon the generation of the rights object.
